Pocket Nocturnal and Tide Computer

The nocturnal is a star clock devised to determine the time at night by using fixed stars visible in the Northern Hemisphere. On the reverse side, a historic tidal computer will help you calculate the time of high tides at your current location. This brass nocturnal is fully functional and can be used in just a few steps. Worn as a decorative pendant or amulet, it is a true eye-catcher that will round off your medieval garb in a beautiful manner. More information...
